Mô hình Lab dựa trên bài lab của thầy Trần Duy Huy
Yêu cầu
1) Cấu hình cơ bản
2) Cấu hình địa chỉ IP như mô hình LAB
3) Định tuyến OSPF giữa Core và Distribution
4) Cấu hình GLBP cho các DS như sau :
- DS 1 : priority 150
weight 150 lower 90 upper 120
chiếm quyền sau 30s
- DS2 : priority 120
weight 120 lower 80 upper 100
chiếm quyền sau 30s
- DS3 : priority default
weight default
chiếm quyền sau 30s
5) Dùng command để kiểm tra các trạng thái của GLBPweight 150 lower 90 upper 120
chiếm quyền sau 30s
- DS2 : priority 120
weight 120 lower 80 upper 100
chiếm quyền sau 30s
- DS3 : priority default
weight default
chiếm quyền sau 30s
6) Cấu hình tracking trên DS1 như sau
- Track line - protocol : interface f0/0 của R1 bị up/down thì giảm weight 80
- Track ip routing : interface f0/0 của R1 bị mất địa chỉ IP thì giảm weight 50
- Track ip route : nếu địa chỉ 1.1.1.0/24 không có trong bảng định tuyến thì giảm weight 40
7) Test- Track ip routing : interface f0/0 của R1 bị mất địa chỉ IP thì giảm weight 50
- Track ip route : nếu địa chỉ 1.1.1.0/24 không có trong bảng định tuyến thì giảm weight 40
Trên client :
- Cấu hình default route chỉ về ip next-hop là 192.168.123.254
- Ping liên tục địa chỉ 1.1.1.1
- Shutdown lần lượt các interface DS1-f0/1 & DS2-f0/0. Sau đó quan sát kết quả
Thực hiện - Ping liên tục địa chỉ 1.1.1.1
- Shutdown lần lượt các interface DS1-f0/1 & DS2-f0/0. Sau đó quan sát kết quả
1) Cấu hình cơ bản

6) Cấu hình tracking
a) Tracking line - protocol
Ta thấy khoảng thời gian từ lúc interface f0/0 bị down cho đến khi Router DS1 chuyển trạng thái từ Active sang Listen là 30s – thời gian preempt, và giá trị weighting đã giảm xuống còn 70
a) Tracking line - protocol
DS1(config)#track 80 interface f0/0 line-protocol
DS1(config)#int f0/1
DS1(config-if)#glbp 1 weighting track 80 decrement 80
Vào shutdown interface f0/0 của R1DS1(config-if)#glbp 1 weighting track 80 decrement 80
DS1(config)#int f0/0
DS1(config-if)#shutdown
DS1(config-if)#shutdown
Ta thấy khoảng thời gian từ lúc interface f0/0 bị down cho đến khi Router DS1 chuyển trạng thái từ Active sang Listen là 30s – thời gian preempt, và giá trị weighting đã giảm xuống còn 70
